On Eileen's insistence that Paul should quit, the actor added: "I don't think he's prepared to compromise on this. He tells her that it's in his blood, pure and simple.

"What he means by that is that it's all he knows. It's his family, at the end of the day. If he's busy protecting Eileen and not being able to open up to her about his own feelings, then he needs the service even more."
